How frequently should collar ties be spaced in a roof system?

The proper spacing for collar ties in a roof system is crucial for providing adequate support and structural integrity. Collar ties are horizontal members that connect opposing rafters in a roof structure and help prevent the roof from spreading due to lateral forces, such as wind or snow loads.

The industry standard for spacing collar ties is typically around 4 feet on center. This spacing allows for sufficient support across the rafters while ensuring that the roof maintains its shape and strength. By adhering to this standard, builders and contractors can ensure that the roof system is compliant with building codes and capable of handling expected loads.

By contrast, spacing collar ties too far apart can compromise the structural strength of the roof, potentially leading to failures or sagging over time. Therefore, 4 feet on center represents a balance between effective structural support and practical construction practices in roof framing.
